Here you can see a list of the 10 most powerful players in the game and the 10 deadliest monsters (decided by how many people they've killed).

A cool feature might be to create a bounty for killing a creature on this list, the higher its level and the more people it's killed the higher the bounty would be. Not sure about that yet, we'll see how much else I can get done this weekend.

My other thought for the town hall is a notice board. A place where players can post short messages for others to read: ie offering gold for a specific item or asking for a healer/thief/warrior/whatever to go on a hunt with them. I'd have to play with how to display such messages, but it could help increase the cooperative side of the game.
